Applied capability
Every module requires an RCA decision, rationale or structured problem-solving response.

A detailed interactive practitioner course for people who investigate failures and manage corrective action. Work through evidence, causal logic, action selection and effectiveness decisions—not passive slide reading.
Individual access £49.99. No VAT is charged. Includes the practitioner workbook, final assessment and certificate.Every module requires an RCA decision, rationale or structured problem-solving response.
The guidance engine highlights missing evidence and explains what needs attention.
The learner can download a completed practitioner workbook containing their structured investigation evidence.
Controlled progression, protected assessment, attempt history and public certificate verification support assurance.
Decide whether an event needs correction only, containment, or a controlled 8D investigation.
Choose evidence that sharpens the problem statement without introducing an assumed cause.
Trace occurrence, escape and system-prevention pathways and identify where evidence is still missing.
Distinguish individual action from the conditions and controls that shaped it.
Select controls that act directly on verified causes and reject weak administrative substitutes.
Decide whether results demonstrate sustained improvement or require the case to remain open.
Separate correction, containment and structured investigation; decide when an 8D response is proportionate.
Define authority, roles, expertise, boundaries and decision ownership before causal analysis begins.
Use is/is-not logic and evidence to describe what, where, when, extent and impact without embedding an assumed cause.
Select immediate controls that protect customers and operations while preserving evidence and avoiding new risks.
Use three-direction 5 Why analysis to test how the problem occurred, escaped detection and was enabled by the management system.
Examine task design, competence, workload, supervision, interfaces and error-likely conditions without defaulting to blame.
Compare solution strength and choose actions that address verified causal mechanisms rather than symptoms.
Assign ownership, control change, confirm implementation and validate that each action performs as intended.
Test where else the same causes, controls or failure pathways could exist across products, processes and sites.
Set leading and lagging measures, review sustained results independently and reopen the case when evidence is insufficient.
Organisations should also evaluate relevant education, investigation experience, observed performance, authority and continuing professional development before assigning an RCA leader.
Each structured decision is retained as controlled learning evidence. After passing, the learner can download a consolidated workbook alongside the verifiable certificate.
